SHAFT-BEARING.

SPECIFIGATIOIN forming part of Letters Patent No. 687,406, datedNovember 26, 1901.

Application filed April 17, 1900. Serial No. 13,244. (No model.)

To all whom it may concern:

Belt known that I, AUGUST RIEBE, m echanical engineer, a subject of theKing of Prussia,

German Emperor, residing at 15 Zwinglistrasse, Berlin, Kingdom ofPrussia, German Empire, have invented certain newanduse:

ful Improvements in Shaft-Bearings; and I do hereby declare thefollowing to be a full,

clear, and exact description of the invention,

to such as will enable others skilled in the art to which it appertainsto make and use the same.

This invention relates to an adjustable shaft-bearingv especiallysuitable for employment as a ball-bearing, the peculiarity of whichconsists in the construction of the folding casing for inclosingadivided race-ring bush, the object being to enable the latter to beadjusted when free from the casing and to be subsequently rearranged tothe exact shaft center-,the closing contrivance,by means of which thetwo parts of the race-ring bush are held together, being temporarilyunfastened for such adjustment.

In the accompanying drawings, Figure l is a transverse section, and Fig.2 a longitudinal section on the line A B of Fig. 1, of a ball-bearingconstructed according to the invention. Figs. 3 and -t are respectivelyan end view and a side view of the same. Fig. 5 is an end view of thedivided ball-bearing race-ring bush. Fig. 6 is a side view of the same.

a is the casing-base, the given position of which determines theposition of the axis of the shaft.

The folding bearing-casing, which is capable of being arranged on aninvariable central line in relation to the base a, consists of 4csegment-a1 parts or clamps p and q, the former of which parts, 19, canturn on the hinge-bolt b in the base a, while the latter, (1, isconnected with the piece 1) by means of the hinge-joint r and terminatesin a slotted shoe-shaped 43 piece to receive the fixing-screw c andhaving a shoulder or bearing-piece s for the nuts to enable the piece 12to be screwed up to the base or. The said screw 0, which is firmly heldby its prismatic head engaging in a hollow in the base a, passes throughthe slot in the shoe-shaped part of the piece q, so that after the nuts.have been loosened it can be shifted and placed out of the range of thepiece g, which can then be turned upward. For the folded or closedposition of the casing it is requisite that an extension of the piece 19should rest against a stop 76, Fig.1,

of the base a.

The ball-bearing bush, Figs. 5 and 6, to be inclosed in the casingp qconsists of a casingring d, which receives the divided race-ring at; forthe balls, the two halves of which casing-ring are joined together bymeans of a hinge e and detachably connected on the other side, wherethey overlap one another, by means of a pin f. The inclosure of theball-bearing bush in front is effected by a disk n, which is provided asa means of adjustment and fits into a screw-thread in the two parts ofthe bush cl, while it is also provided with a packing-ring surroundingthe shaft to. A similar packing-ring is introduced at the back, wherebythe lubricating material is prevented from running out of the interiorof the bearing. The remainder of the ball-bearing arrangement itself isnot essential to the present invention. It may be observed that forholding the two rows of balls in the form of the invention shownsheet-metal rings are inserted and that the running-surface is formed bymeans of a ring surrounding the shaft to. The adjustable ball-bearingbush thus arranged or a similarly-constructed bearing-piece is placedinside the casing, consisting of the segmental clamps 1) q. As inSellers bearing, the hearing has a certain mobility in consequence ofthe spherical formation of the bearing-surfaces, which fit one another,as will be seen at Fig. 2. The efiective bearing-surfaces of the casingserving for the exact centering of the hearing are placed at positionsin the segmental clamps p q lying opposite to one another and arediscontinued at other parts.

The form of construction described enables the bearing to be adjustedand precisely rearranged in the following man ner: The screw 0 isloosened and the casing formed by the segmental clamps p q turned back,so that the bush d is exposed on all sides. If the ex- LOO posureextended only to a part of the circumferenceas, for example, by theremoval of an ordinary bearingcover-the object of a complete exposure ofthe bearing would not be attained. The part of the hearing held disk 77.after a detent 7 Figs. 2 and 3, which serves for keeping the bearing inthe adjusted position, has been unscrewed. Further, the bush can beopened after thepin f has been taken out for the purpose of examining orcleaning the interior. When the adjustment has been effected and thebush runs properly on the shaft w, the casingp q is folded down for thepurpose of inclosing.

it, the nuts of the screw 0 being screwed tightly against the shoulder sof the piece q, the two segmental clamps close on the bush d and shaftw, and the latter is forcibly adjusted to the exact axial center. By theresting of the foot of the clamp 10 on the stop is the invariablecentering posit-ion is attained, so that the center of the shaft isforced to take the original position. At the same time the temporaryclosing contriva nce of the ballbearing bush d, which consists of thepinf, is released, so that the strain is taken up by the casing.

The feeding of the lubricating material to the bearing can be effectedby means of a hole 0 in the bush cl, in the interior of which aspring-valve 2, Fig. 1, is so arranged that it forms an automaticclosing contrivance, preventing the lubricating material from runningout. The hole 0 is accessible by means of a corresponding hole 15 in theclamp p.

The folding arrangement of the interior bush enables the bearing to beconveniently cleaned and the sliding surfaces and balls to be examinedeven when the space adjoining the shaft-bearing is limited. In the caseof the employment of a closed bush the rings would have to be pushed.out sidewise, for, which purpose more room would be requisite.

It is obvious thatinstead of the ball-bearing another insertedbearing-piece capable of automatic adjustment can be placed inside thefolding casing.

What I claim is- 1. The combination with a casing composed of sectionshinged together, a base, a hingejoint connecting one end of said casingwith said base, and a fixing-screw connecting the other end of saidcasing with said base, of a shaft-bearing having an adjustable bushseparate from said casing, said bush being divided and arranged to openout in order that the bearing may be readily opened and eX-' amined.

2. The combination with a casing composed of sections hinged together, abase, a hingejoint connecting one end of said casing with said base, anda fixing-screw connecting the other end of said casing with said base,of a shaft-bearing having an adjustable bush separate from said casing,said bush being divided and arranged to open out in order that thebearing may be readily opened and examined, and a pin serving as apreliminary closing contrivance for holding the parts of said bushduring adjustment.

In witness whereof I have hereunto set my hand in presence of twowitnesses.
